I have a Mk4 2.2 titanium x sport and have a factory fitted reversing camera fitted.

Today, for some bizarre reason, when I put the car in reverse, it flickered for a second then turned off! The next time I engaged reversed, the camera did not even attempt to show. The sensors still work but I'm getting nothing on the display?!

Im going through the process now of ordering a camera and getting it installed, seems a fairly simple process and I will use it in conjunction with sensors. The mondeo rear window is not ideal for seeing small things like children, so I find I will use it all in conjunction with one and other and get the best peripheral vision.
